Invisco Whole House Fan Company has just created and has a patent pending on round cube core grilles with a thin shiny white plastic frame for the ultimate look in a home or office. Cube core grilles are typically done with 1/2 inch square openings and very thin edges so that air flow is maximized and air resistance is minimized.
